Detailed Description

The TQDomDocumentFragment class is a tree of TQDomNodes which is not usually a complete TQDomDocument.

If you want to do complex tree operations it is useful to have a lightweight class to store nodes and their relations. TQDomDocumentFragment stores a subtree of a document which does not necessarily represent a well-formed XML document.

TQDomDocumentFragment is also useful if you want to group several nodes in a list and insert them all together as children of some node. In these cases TQDomDocumentFragment can be used as a temporary container for this list of children.

The most important feature of TQDomDocumentFragment is that it is treated in a special way by TQDomNode::insertAfter(), TQDomNode::insertBefore(), TQDomNode::replaceChild() and TQDomNode::appendChild(): instead of inserting the fragment itself, all the fragment's children are inserted.

Member Function Documentation

TQDomDocumentFragment::TQDomDocumentFragment ()

Constructs an empty document fragment.

TQDomDocumentFragment::TQDomDocumentFragment ( const TQDomDocumentFragment & x )

Constructs a copy of x.

The data of the copy is shared (shallow copy): modifying one node will also change the other. If you want to make a deep copy, use cloneNode().

TQDomDocumentFragment::~TQDomDocumentFragment ()

Destroys the object and frees its resources.

bool TQDomDocumentFragment::isDocumentFragment () const `[virtual]`

This function reimplements TQDomNode::isDocumentFragment().

See also nodeType() and TQDomNode::toDocumentFragment().

Reimplemented from TQDomNode.

TQDomNode::NodeType TQDomDocumentFragment::nodeType () const `[virtual]`

Returns DocumentFragment.

Reimplemented from TQDomNode.

TQDomDocumentFragment & TQDomDocumentFragment::operator= ( const TQDomDocumentFragment & x )

Assigns x to this DOM document fragment.

The data of the copy is shared (shallow copy): modifying one node will also change the other. If you want to make a deep copy, use cloneNode().
